PROPORTIONAL METER.

To all 2077,0171, it may concern.-

Be it known that I, JAMEs O. ANDERSON, a citizen of the United States,residing at Highland Park, in the county of Lake and State of Illinois,have invented certain new and useful Improvements in ProportionalMeters; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

My invention relates to certain new and useful improvements inwatermeters, and while especially adapted to a proportional meter, suchas illustrated and described in an application filed concurrentlyherewith and bearing Serial N 0. 161,564, may be in part employed inconnection with a meter such as is shown and. described in LettersPatent No. 711,192, granted to me on the 14th of October, 1902.

My presentinvention has for its object to not only guard against anyfraudulent alteration of the controller or valve employed in theconstruction shown in my above-referre dto application, but to alsoguard against the reversal of the connection between such a meter asthat shown in my Letters Patent referred to or any other meter with thesupply pipe or main and to thus prevent th reversal of the registeringmechanism of the meter.

In the drawings forming part of this application, and which areduplicates of those accompanying the concurrent application referred to,Figure 1 represents in perspective a meter and proportional couplingconnected. with an ordinary main or supply pipe, the meter being of suchconstruction as that shown and described in the Letters Patent grantedto me, as hereinbefore stated. Fig. 2 is a central vertical section ofthe auxiliary passage or coupling shown and described in the concurrentapplication hereinbefore referred to. F ig. 3 relation of the parts asshown in at Fig. 1, and Fig. 4 is on the line a: in of Fig. 2.

Similar numerals represent like parts in the several figures.

1 represents an ordinary main or conduit perspective a detail sectiontaken plpe, 2 a couplmg such as described in my concurrent applicationfor proportionately dividing the main body of water delivered by the mamor conduit, and 3 a meter such as Specification of Letters Patent.Application filed June 15, 1903. Renewed March 22, 1907. Serial No.

[ described in my Letters Patent hereinbefore referred to.

4 represents an ordinary leading from the coupling 1 pipe, as the casemay be, and communicating i with a meter 3, and 5 is a pipe connectedwith the opposite side of the meter and leading back to the coupling 2or main. In either case the pipes 4 and 5 are secured to the meter bypolygonal coupling-nuts 6, and the cap 7, which protects and guards theregis tering mechanism of the meter, is locked in position in the mannerdescribed in Letters Patent No. 711,191, granted to me October 14, 1902.The cap 7 has formed integral therewith yokes or arms 8, the ends ofwhich terminate in forks 9, adapted to embrace the conduit or a pipe 2or a mam supply polygonal nuts 6, as clearly shown at Figs. 1

and 3, so that when the parts are properly assembled and the cap 7 issecurely locked in position by the locking devices described in myLetters Patent N 0. 711,191 the couplingnuts 6 cannot be removed, andhence the established relation between the meter and the main or conduitor the coupling 2, as the case may be, cannot be altered, and hence theaction of the meter cannot be reversed, as might be the case if no othermeans for preventing such action be not provided.

When my present invention is employed in connection with the coupling 2such as described in my concurrent application, it will be readily seenthat when the pipes 4 and 5 have been connected to the coupling 2 by anordinary screw-joint and their opposite ends I have been connected withthe meter 3 by the coupling-nuts 6 the relation between the meter andthe coupling has become fixed and cannot be fraudulently altered.

10 are the heads cylinder by a screw-thread, as fully described. in mypatent hereinbefore referred to, and to I prevent any fraudulent removalof said ca s I provide the same with one or more radial lugs 11 and thecap 7 of the registering mechanism. with arms 12, which, as shown atFig. 1, have their free ends located outside of the lugs 11 a sufficientdistance to permit of the necessary rotation of the heads to tighten thesame when necessary but when i an effort be made to remove the head 10it will be seen that the lug or lugs 11 will, ac-

cording to the distance the cap is moved, be

the extremity of the arm 12, and conseof the meter secured to the 5 ICCIIO

quently the lug will contact with said arm and continued rotation of thehead will be hence access to the interior impossible, and

and no false adof the meter is prevented justments can be made.

When the meter is used in connection With the novel coupling 2, such asdescribed in my concurrent application hereinbefore referred to, Iprovide that portion of the coupling which constitutes the secondarywaterpassage therein, and in Which is located the controller or pistonvalve 13, the spring 14, and adjusting ring-nut 15, with a threadedbushing 16 at each end of the secondary passage or water-channel, and tothis bushing I secure by a screw 17 the stationary portion 18 of such alocking mechanism as that described and illustrated in my Letters PatentNo. 711,191, heretofore referred to, so that when the part 19 of thelock is turned into locking position access to the valve or controllerand its adjusting devices is prevented, and consequently the adjustmentof the controller cannot be altered to fraudulently change theproportional division of the column of Water flowing through the main tocause a fraudulent registration by the meter.

As fully described in my concurrent application hereinbefore referredto, the locking devices at each end of the coupling 2 also permit of theready machining of the passage in which the controller and its adjustingdevices are located and the ready assembling and adjustment of the same.

From the construction and arrangement shown and described it will bereadily seen that after a meter has been properly located to accuratelyregister the quantity of Water passed through the main and used by aconsumer no alterations can be made except by a person having possessionof the combi nation or key of the locking devices of the cap of theregister or the locking devices at each end of the passage in which thecontroller is located.

Having described the construction and advantages of my improvements,what I claim as new, and desire to secure by Letters Patent, is-

1. In combination with a-meter-cylinder closed by heads adapted to besecured in position by a threaded connection with the cylinder andprovided with radial lugs or projections, a cover or cap locked in(position to protect and guard the registering evices and rovided with afixed arm extending within the rotative plane of the lugs or projectionson the heads of the cylinder and adapted to contact therewith, wherebyfraudulent removal of the heads is prevented, as hereinbefore set forth.

2. In combination with the meter and registering mechanism, and inletand outlet pipes connected with the meter by polygonal couplings; a capor cover locked in osition over the registering mechanism an formed withrigid integral yokes' terminating in forks adapted to embrace thepolygonal couplings, whereby both the registering mechanism and thepolygonal couplings are protected against fraudulent manipulationsubstantially as hereinbefore set forth.

3. In a meter provided with a coupling intermediate of the mainsupply-pipe and the meter and formed with a passage for, and providedwith a controller-valve for proportionately dividing the column of waterdelivered through the main supply-pipe; a threaded bushing secured inposition at the end of the valve-seat; a lock member secured to thethreaded bushing by a screw, and a second lock member located Within thelock member attached to the bushing and adapted to be locked to thefirst-named lock member, substantially as and for the purpose set forth.

In testimony whereof I aflix my signature in presence of two witnesses.
